Acrylic acid or NIPAM are included in the aqueous phase of a high internal phase emulsion, while the oil phase includes styrene. Polymerisation of such high internal phase emulsions (HIPEs) yields macroporous polymers (polyHIPEs) with a scaffold composed of cross-linked polystyrene and domains of cross-linked poly(acrylic acid) or cross-linked poly(NIPAM) positioned inside the cavities of the polystyrene skeleton. Monolithic discs are shaped from PS/PAA and PS/PNIPAM polyHIPEs in order to study the dependence of flow resistance through the discs in relation to pH or temperature changes.
